Young planetary systems offer a unique advantage in that their spectral signatures are representative of primordial formation conditions. This is significantly advantageous when compared with more evolved planets which have experienced significant stellar irradiation, processing and pollution. The formation mechanism and subsequent evolution of massive, short-period planets is not currently well understood. For example, these planets may have formed at large distances and migrated inwards or alternatively formed in situ. Here, we propose to obtain spectra during 4 transits of AU Mic b, the innermost Neptune-sized planet in the system (Teq = 820K), with NIRCam F322W2/F444W (2.4 - 5 micron). Our primary objective is to measure atmospheric C/O and metallicity to constrain the formation location of the 17613( 11) - 21-Apr-2025 18:11:24 - [ 2] planet. We propose for simultaneous JWST + HST observations. The chemistry in the atmosphere of AU Mic b will be dictated by the environmental ultraviolet flux. Because AU Mic is both young and a flare-active star, we require FUV observations to (i) identify and remove stellar flares from our transmission spectrum and (ii) characterize the FUV environment, which will be crucial for interpreting our planet spectrum. These observations will also provide unique FUV - NIR measurements of flare events, furthering our understanding of stellar magnetism. These spectra will provide an important legacy for understanding young stars, planetary atmospheres, and combining NIR + FUV to mitigate stellar contamination. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will observe four transits of AU Mic b simultaneously with JWST in order to monitor for stellar flares which are likely to occur during these observations. We will use the COS G130M setting with CENWAVE=1222 angstroms. This provides coverage from approximately 1060 - 1360 angstroms with a detector gap from 1210-1225 angstroms. This setting includes several emission lines which will be used to identify and characterize stellar flares (e.g. C III at 1175.95 Angstrom and Si III at 1294.55 Angstrom). The same COS setting will be used for all observations. This observing mode and setup have been used in previously successful HST programs (e.g. HST GO 16164). AU Mic is visible for 3000 seconds during an HST orbit. Assuming a total exposure time of 3000 seconds, we expect to achieve a S/N of 75 - 100 in the C III lines. Our observations must occur during transits of AU Mic b, which has an orbital period of 8.46321 days and a transit duration of 3.5 hours. According to the APT visit planner, there are ~20 possible transits visible during Cycle 32 and JWST Cycle 3, during which our observations should be scheduled. This should be feasible to schedule our simultaneous observations. AU Mic b experiences transit timing variations. We are actively monitoring this system to account for these variations. The uncertainty on the period is 0.00004 days. The current uncertainty on the transit mid-point is 0.0007 days. In order to obtain the longest out-of-transit baseline for each transit, we will stagger the out-of-transit observations for each visit in the following way: for 2 out of 3 transits we will obtain 2 pre-transit exposures and for 1 out of 3 transits we will obtain 2 post-transit exposures. Each transit will have 3 in-transit exposures. We believe this strategy is optimal so that the out-of-transit baseline extends as far as possible from ingress or egress, minimizing the possibility of a highly extended atmosphere creating pre- or post-transit absorption that could skew the in-transit absorption depths. With this strategy in mind, each visit must be scheduled no earlier than planetary orbital phase 0.97 and no later than 0.99. AU Mic is a pre-main sequence M-star with effective temperature T=3700+-100 K and must be considered under the Bright Object Protection Considerations for M Dwarf Flare events (Osten 2017). It exhibits flares with energy <= 10^30 ergs twice an hour (Feinstein et al. 2022). This can be compared to the active flare star AD Leo which experiences a flare with the same energy 5 times per day. 17613( 11) - 21-Apr-2025 18:11:24 - [ 3] From three archival visits to AU Mic, the star did not exhibit a flare with energy > 10^30 ergs, and thus is unlikely to exhibit a superflare during these proposed observations. Our selected COS configuration does not include the strongest FUV lines (e.g. Ly-alpha) which would otherwise cause damage to the detector. All emission line fluxes in our configuration are within the safe range for active M dwarfs. ------------------------------------------------------------------------------------ 17613( 11) - 21-Apr-2025 18:11:24 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-AU-MIC STAR, EXTRA-SOLAR RA=20H45M9.8729S +/- .038", J2000 V = 8.627 PLANET, EXTRA-SOLAR DEC=-31D20'32.82" +/- .027" PLANETARY SYSTEM, PRE-MAIN SEQUENCE STAR Reference Frame: ICRS Extended: NO Comments: This object was generated by the target selector and retrieved from the SIMBAD database.
